Specification of Lettera Patent.

Patented May 12, 190B.

Application filed February 21, 1908. Serial No. A17,018.

To all `whom 'it may concern:

Be it known that I, JACOB FINE, citizen of United States residing at Louisville, in the county of Je erson and State of Kentucky, have'invented certain new and useful Imrovements in Car-Brakes, of which the folowing is a specification.

My invention relates to car brakes embodying braking members for engagement with, the car wheel, and with the track rail adjacent the wheel, and the ob'ect thereof is to provide a more efiicient eviee of this character, in which the engagement of the braking parts willbe more positive in their S' action.

My invention further and s eciiically resides in the following features ofpeonstruction, arrangpment and operation, to be hereinafter decori ed with reference to the accom anying drawings forming a part of this speci cation, in which like numerals are used to designate like arts throughout the several figures, and in w ich,

Figure 1 is a side elevation of my improved mechanism. Fig. 2 is a rear elevation thereof, and Fig. 3 is a side elevation of the rail brake operating arm detached.

in the practical embodiment of my iiivention, I provide a brake beam 5, standin transversely beneath the body of the car and provided with brake shoes to engage the peripheral face ofthe alined pairs of wheels 7 mounted upon an axle 8. The member beam .3 of the forward and rear pairs of wheels 7, ma be connected if desired by a chain 9, sai( brake beams being swun r from the body of the car by chains 1() and eilig connected to the brake rod 11 by a chain 12, to be drawn towards the wheels 7 by the rotation thereof. The brake beam 5 is horizontally slidably mounted through a longitudinal slot 13 in the horizontal arm 14 of a rail brake operating member 15, having a tubular portion 16 alined with said horizontal arm 14,

and loosely mounted about the wheel axle 8.'

'lhe rail brake operating member 15, is provided with an an ruler downwardlyextending arm 17, having a ongitudinal slot 18 therein, ad'acent the end thereof, said member 15 being mounted u on the wheel axle 8 upon the inner side an( adjacent the wheels 7, as shown in Fig. 2.

Extending downwardly from the body of the car and bolted thereto by bolts 1i), is a bracket 20, arranged upon the inside and adjacent the member l5. Fivotally mounted upon the outside, and having its pivot pin 2i extending through the lower end of the bracket 20, is a bolt-crank-lever 22, provided upon its up er end with a projecting pin 23,

extendin t irough the slot 18 in the angular arm 17 o the member 15. The bolt-cranklever 22 is provided adjacent the end of its lower horizontal portion, with spaced ears 26, having a bolt 27 projecting vertically therethrough aiid forming a pivot for a horizontal arm 28 extending approximately arallel of the bolt crank lever 22 and provided upon its free end with a 'rail shoe 24 pivotally conneoted thereto at 25. By otal connection, at the bolt 27, the rail shoe carrying arm 28 may swing laterally to allow the same to'inaintain engagement with the rail when the same is rounding a curve, such swinging movement being tension/sd by a spring 29 surrounding the pivot holt 27.

From the foregoing it will be seen that when the brake rod 1l is rotated to draw the brake beam 5 toward the wheel 7, thc wheel shoes 6 carried thereby, will contact with seid wheels with a brake connection, and by reason of which engagement, and in view of the rotation of the wheel 7'iii the direction oi the arrow in Fig. 1, the rail brake operating member 15 will be swung upwardly upon the wheel axle 8, swinging thc bell-crank-lever 22 upon its pivot 21, and forcing the rail shoe 24 into close braking engagement with the rail A. When the brake rod 11 is released, the mechanism will be returned to its normal released position, as shown in Fig. 1, by means of a retractile coil spring 26', connected to and extending between the outer end of the horizontal arni 14 of the. member 15, and the bracket 20 adjacent its lower end. The bracket 2() is provided with stop pins 3U and 3l extending outwardly toward the wheel 7, and rcs iectively defining the limits of the downwart and u )ward movement oi the horizontal arm 14 o the member 15 b v reason of the frictional contact of the wheel slices ('i.

From the foregoing apparent description, it will be that l provide a highly ellicient device. which will be as readily and easily oper 1'1- ated as the ordinary brake and in which the contact of the parts will be positive and unfailing in its action.

ilaving fully described my invention, claim:

1v ln a earbrakeof thecharacterdescribed, the combination of a. wheel brake and menu` virtue of its pivfor moving the same toward its wheel, of a rocking member loosely pivotally mounted about the wheel axle, and having an arm to which said wheel brake. is slidably connected to move toward its wheel, whereby said member will be rocked by the frictional contact between said wheel shoe and the rotating wheel, Va rail brake suitably mounted to be moved into engagement with the rail adjacent said wheel, and connections between said rail brake and said rocking member for moving said rail brake into engagement with the rail upon the rocking thereof, substantially as described.

2. In a car brake of the character described, the combination of a wheel brake and means for moving the same toward its wheel, of a rocking member loosely )ivotally mounted about the wheel axle an having an arm to which said wheel braiic is slidablv connected to move toward the wheel, whereby said member will be rocked by' the frictional contact between said wheel shoe and the rotating wheel, a rail brake suitably mounted to be moved into engagement with the rail adjacent said wheel, and means for limiting the rocking movement of said member, substantially as described.

3. Inacar brake of the charaeterdescribed, the combination of a wheel brake and means for moving the same toward its wheel, of a rocking member loosely )ivotally mounted about the wheel axle, and having an arm to which said wheel brake is slidably connected to move toward its wheel, whereby said member will be rocked by the frictional contact between said wheel shoe and the rotating wheel, a rail brake suitably mounted to be moved into engagement with the rail adjacent said wheel, and means for returning said rocking arm to its normal position upon the release of said wheel brake, substantially as described.

4. In a car brake of the character described thc combination oi a wheel shoe, and means ier moving the same into engagement with thc wheel, a rocking member to which said shoe is connected to move toward its wheel, and adapted to be rocked by the frictional engagement of said wheel brake with said wheel, a rail brake suitably mounted adjacent said wheel, and means within said connections to allow of the lateral swinging movement of said roller, substantially as described.

5. In a ear brake of the character described, the combination ol` a wheel bralic and means for moving the same toward its wheel, of a rocking member loosely pivotally mounted about the wheel axle., and having an arm to which said wheel brake is slidably connected to move toward its wheel, whereby said member will be rocked by the frictional contact between said wheel shoe and the ro tating wheel, a rail bralie suitably mounted to be moved into engagement with the rail adjacent said wheel and means within said connections to allow of the lateral swinging movement of said roller, substantially as described.
